OPGW Product Description
Central loose tube
type
The fibers is placed loosely in a sealed and water resistant stainless
steel tube filled with water blocking gel. This tube provides protection to the fiber during installation and operation under severe environmental conditions. Aluminium layer over
the tube is optional. The stainless optical tube is located at the center of the cable protected by single or multiple layers of aluminium clad steel and aluminium annoy wires. The
aluminium clad steel wires are shaped trapezoidally around the optical unit to provide compact construction. The metallic wires provide mechanical strength to withstand severe
installation and operating conditions, while achieving conductivity to controltemperature rise during short circuit conditions.
Multi loose tube
ty
Multiple loose tube
type
The fibers is placed loosely in a sealed and water resistant stainless
steel tube filled with water blocking gel. Two or three stainless steel optical tubes are helically stranded in the inner layer of a multiple-layer strandard cable. The multiple
loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144. The multiple loose tube type can meet the requirement of huge cross
and large current capacity.
Application
1.The Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines
with
double function of ground wire and communication. Especially for installation on normal
voitage and
extra highvoltage power lines. OPGW can replace conventional ground wire of old power line
with
increasing fiber communication function. They conduct short circuit current and provide
lightning resistance.
2. OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements,
mostly used in new lines. Its applications are:high pressure over 110kv, with a longer span (usually over 250M).
